Overview
Mermaid diagram (expand to render)
The DLX5 gene encodes Distal-Less Homeobox 5, a member of the DLX family of homeodomain transcription factors essential for craniofacial development, limb formation, and central nervous system development. DLX5 plays crucial roles in the development of GABAergic inhibitory [neurons](/entities/neurons) in the forebrain, particularly in the olfactory bulb, cerebral [cortex](/brain-regions/cortex), and basal ganglia. Located on chromosome 7q22.1, this gene is part of a conserved gene cluster with DLX6, and both are co-expressed during development.
Gene Structure and Regulation
The DLX5 gene spans approximately 4.5 kb and contains 3 exons encoding a protein of 325 amino acids. Key regulatory features include:
